Permeable Paving Design Guide
Examples of SUDs Techniques
Utilising green areas to provide
natural filtration is known as 'soft
SUDs'. Using man-made materials to
achieve the same result is referred to
as 'hard SUDs'. The following is a list of
soft SUDs techniques, and examples
of how we can integrate soft and
hard SUDs to achieve a practical and
holistic solution.
Filter strips – wide gently sloping area of grass or dense
vegetation that filters storm water run-off from impermeable
areas
Swales – generally wide shallow grass lines channels intended
to transport or store storm water run-off and allow infiltration
Infiltration Basin – surface depressions in the landscape
intended to store storm water and allow infiltration
Wet ponds – used to store storm water run-off and are
permanently wet and provide amenity features
Detention basins – used to store storm water run-off but are
only wet following a storm event
Wetlands – shallow ponds with vegetation intended to reduce
pollutants in storm water run-off
Filter drains – trenches filled with permeable material
Soakaways – buried storage point for storm water run-off
where it will infiltrate into the ground
Green Roofs – planted roofs which slow and reduce the
amount of run-off whilst also providing a host of biodiversity
benefits
Rills – open surface channels which transport water cleanly and
safely from one point to another (frequently employed as an
aesthetic consideration)
Permeable Paving – hard surfaced areas which allow water to
permeate through the surface and into the ground at source

Adopting wider use of these features will
make a marked difference to our landscapes,
improving habitats for wildlife and flora
and reducing the risk of flooding. However,
we cannot ignore the growing need for
hardstanding. People need to drive and park
vehicles, ride bikes, and push prams and
wheelchairs comfortably and easily. We all
enjoy aesthetically appealing public spaces
which retain their clean, sleek looks with the

minimum of maintenance. even taking into
account the growing awareness of green
issues, we have to accept that we all want
to go about our modern lives with the least
amount of mess and difficulty; hard standing
is here to stay.
So, the question is: how do we satisfy these
modern requirements whilst mitigating the
effects of water stress?
